Guarantees and Surety Bonds</b> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">We have issued parental guarantees and obtained surety bonds on behalf of our subsidiaries, including credit support instruments enabling APSES to offer energy-related products and surety bonds at APS, principally related to self-insured workers’ compensation. Non-performance or non-payment under the underlying contract by our subsidiaries would result in a payment liability on our part under the guarantee or surety bond. No liability is currently recorded on the Condensed Consolidated Balance Sheets related to such instruments. At March 31, 2011, we had no outstanding claims for payment under any of these instruments. Our guarantees and surety bonds have no recourse or collateral provisions to allow us to recover amounts paid under these instruments. The amounts and approximate terms of our guarantees and surety bonds for each subsidiary at March 31, 2011 are as follows (dollars in millions): </div> <div align="center"> <table style="font-size: 10pt; text-align: left" cellspacing="0" border="0" cellpadding="0" width="100%">  <tr valign="bottom"> <td width="44%"> </td> <td width="3%"> </td> <td width="1%"> </td> <td width="9%"> </td> <td width="1%"> </td> <td width="3%"> </td> <td width="1%"> </td> <td width="9%"> </td> <td width="1%"> </td> <td width="3%"> </td> <td width="1%"> </td> <td width="9%"> </td> <td width="1%"> </td> <td width="3%"> </td> <td width="1%"> </td> <td width="9%"> </td> <td width="1%"> </td> </tr> <tr style="font-size: 10pt" valign="bottom"> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="6" style="border-bottom: 1px solid #000000">Guarantees</td> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="6" style="border-bottom: 1px solid #000000">Surety Bonds</td> <td> </td> </tr> <tr style="font-size: 10pt" valign="bottom"> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2">Term</td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2">Term</td> <td> </td> </tr> <tr style="font-size: 10pt" valign="bottom"> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000">Amount</td> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000">(in years)</td> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000">Amount</td> <td> </td> <td> </td> <td nowrap="nowrap" align="center" colspan="2" style="border-bottom: 1px solid #000000">(in years)</td> <td> </td> </tr>   <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:30px; text-indent:-15px">APSES </div></td> <td> </td> <td align="left">$</td> <td align="right">5</td> <td> </td> <td> </td> <td> </td> <td align="right">1</td> <td> </td> <td> </td> <td align="left">$</td> <td align="right">60</td> <td> </td> <td> </td> <td> </td> <td align="right">1</td> <td> </td> </tr> <tr valign="bottom"> <td> <div style="margin-left:30px; text-indent:-15px">APS </div></td> <td> </td> <td> </td> <td align="right">4</td> <td> </td> <td> </td> <td> </td> <td align="right">1</td> <td> </td> <td> </td> <td> </td> <td align="right">9</td> <td> </td> <td> </td> <td> </td> <td align="right">1</td> <td> </td> </tr> <tr style="font-size: 1px"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 1px solid #000000"> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 1px solid #000000"> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr valign="bottom" style="background: #cceeff"> <td> <div style="margin-left:15px; text-indent:-15px">Total </div></td> <td> </td> <td align="left">$</td> <td align="right">9</td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td align="left">$</td> <td align="right">69</td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr style="font-size: 1px"> <td> <div style="margin-left:15px; text-indent:-15px">  </div></td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 3px double #000000"> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td nowrap="nowrap" colspan="2" align="right" style="border-top: 3px double #000000"> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr>  </table> </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">APS has entered into various agreements that require letters of credit for financial assurance purposes. At March 31, 2011, approximately $44 million of letters of credit were outstanding to support existing pollution control bonds of similar amount. The letters of credit are available to fund the payment of principal and interest of such debt obligations. These letters of credit expire in 2011 and 2013. APS has also entered into approximately $54 million of letters of credit to support certain equity participants in the Palo Verde sale leaseback transactions (see Note 7 for further details on the Palo Verde sale leaseback transactions). These letters of credit were amended and extended in April 2010, and will expire in 2013. </div> <div align="left" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">We enter into agreements that include indemnification provisions relating to liabilities arising from or related to certain of our agreements; most significantly, APS has agreed to indemnify the equity participants and other parties in the Palo Verde sale leaseback transactions with respect to certain tax matters. Generally, a maximum obligation is not explicitly stated in the indemnification provisions and, therefore, the overall maximum amount of the obligation under such indemnification provisions cannot be reasonably estimated. Based on historical experience and evaluation of the specific indemnities, we do not believe that any material loss related to such indemnification provisions is likely. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="center" style="font-size: 10pt; margin-top: 0pt"> <b> </b> </div> </div>  <!-- Begin Block Tagged NotefalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringProvides pertinent information about each guarantee obligation, or each group of similar guarantee obligations, including (a) the nature of the guarantee, including its term, how it arose, and the events or circumstances that would require the guarantor to perform under the guarantee; (b) the maximum potential amount of future payments (undiscounted) the guarantor could be required to make under the guarantee; (c) the current carrying amount of the liability, if any, for the guarantor's obligations under the guarantee; and (d) the nature of any recourse provisions under the guarantee, and any assets held either as collateral or by third parties, and any relevant related party disclosure.
